    My take on this is the following: In science many things are named after the people who discovered or were involved in developing things...I think your question is related to the QRS detection Algorithm by Pan J and Tompkins. P for Pan and T for Tompkins. Maybe you could research more under Bio Medical Engineering :wink2:
    The sequence is P QRS T, this stuff will come up for us next. Maybe my smart teacher knows more, I'll ask
    In the meantime I will continue riding the WW wave.
    That theory shows a lot of thought, but the naming of EKG components goes way, way back. Einthoven named the components in the late 19th century. No one knows the reason for PQRST with any certainty. A couple of popular theories:

    - Einthoven was heavily influenced by the work of Rene Descartes, 17th century philosopher and mathematician, who used P to name the first point on a given curve. The rest of the letters just followed naturally.

    - Einthoven thought PQRST was good because they are close to the middle of the alphabet, allowing room for additions later. (The U wave was in fact discovered before long.)

    Naming it after themselves, Isnt that a "full of themselves" attitude. You are probably right.
    Haven't had a good laugh this early in the a.m. for a while
    Maybe we can have a " funniest named after themselves" contest...I can't think of anything right off....

    Does anyone know of a good animation that shows how bloodpressure works?
    I've been trying to find stuff online but have not been successful.
    Thanks in advance :wink2:

    i am takin a & p 2 currently at glendale community college in arizona and think it is awesome. we are learning about the heart and all the fun things that come along with that. i find this course easier than a &p 1 cuz i learned my ways of studying for the lab practicles and lecture exams. I cheat......not really but i video tape the labs and watch it a few times before the lab prac. i am the only one who i see doing this, the instructor doesnt mind...but why doesnt anyone else do it?!? do any of you?

    OMG...I can just see myself coming in there with a camcorder....and everybody WHINING!!!!! I think some are already nervous about the taperecording which is ok in my class. Videotaping may not be allowed in my school, I am not sure what the policy is on that one.
    Most of them in my class would probably like to see me dead anyhow...I ahvae the highest grade and I am foreign and may make it into nursing school before they do.....one student in particular was rude to me for the second time since classes started. All I can say is that I have my cellphone near and I know how to call 911 should anyone assault me.

    Eric -- Thanks for that great information!! That is very cool

    As for my test, I didn't do so hot. I'm still not sure what I made because she hasn't graded my essay questions, but lemme just say that my scantron had too much red on it

    I am sorry you didnt do as well as you wanted to. When you get the tests back and go over them, look at it real good and try to make note of what the instructor tests over. (notes, material in the book,or something else that was used. Then for the next tests, focus on that. Dont get discouraged. Hang in there.

    So, how is everyone doing?
    We were off on Monday and since we missed he was on fire today :angryfire and flew through the lab material and lecture material with super sonic speed.
    For our next lab test we need to know major arteries and veins of the body, fetal circulation. We will also have to identify bloodvessels in the fetal pig which we will start working with next Monday. Once again, lots of memorization. We started the chapter on bloodvessels in lecture also.
    Good luck everyone....1/3 of the grade is pretty much done.

    Oh, man. We are studying the veins and arteries also, but we dont get to do any disecting.

    I'm sorry you don't have a fun lab....maybe it's a blessing that you don't have to mess with that stinky little piggy The fermenting sheep hearts were enough, I tell you!!!! At least he was able to then get us some fresh pig hearts...but still it is quite gross.
    I am sooooo NOT looking forward to it
  12. by   lisabeth
    Yes, the stinky is bad, but I learned soooo much by disecting, and I want to do that again.

    You just don't learn it from pictures as you do from the "real thing" since it's three dimensional.
    I will make copies of the pictures in the book so that I can practice labeling all the different vessels and start memorizing them. He is very good about telling us what we need to know, I really appreciate that about him.
    I am just afraid that I mix up the arteries and veins
